“…A study of bacterial attachment to clays showed that most 2:1 clays enhanced respiration, while 1:1 clays had minimal effect (43). It has also been observed that positively charged surfaces can reduce cell viability (13,26,44,47). Unfortunately, given these disparate results, the prediction of how a specific surface may affect bacterial metabolic activity remains elusive.…”

Bacterial adhesion to natural and man-made surfaces can be beneficial or detrimental, depending on the system at hand. Of vital importance is how the process of adhesion affects the bacterial metabolic activity. If activity is enhanced, this may help the cells colonize the surface, whereas if activity is reduced, it may inhibit colonization. Here, we report a study demonstrating that adhesion of both Escherichia coli and Bacillus brevis onto a glass surface resulted in enhanced metabolic activity, assessed through ATP measurements. Specifically, ATP levels were found to increase two to five times upon adhesion compared to ATP levels in corresponding planktonic cells. To explain this effect on ATP levels, we propose the hypothesis that bacteria can take advantage of a link between cellular bioenergetics (proton motive force and ATP formation) and the physiochemical charge regulation effect, which occurs as a surface containing ionizable functional groups (e.g., the bacterial cell surface) approaches another surface. As the bacterium approaches the surface, the charge regulation effect causes the charge and pH at the cell surface to vary as a function of separation distance. With negatively charged surfaces, this results in a decrease in pH at the cell surface, which enhances the proton motive force and ATP concentration. Calculations demonstrated that a change in pH across the cell membrane of only 0.2 to 0.5 units is sufficient to achieve the observed ATP increases. Similarly, the hypothesis indicates that positively charged surfaces will decrease metabolic activity, and results from studies of positively charged surfaces support this finding.Bacterial adhesion and biofilm formation are important to a wide array of fields, such as environmental, chemical, and biomedical engineering; food processing; materials science; marine science; and ecology and environmental sciences. A key consideration in the development of a biofilm is the initial interaction between the bacterium and the substrata and the way in which these interactions affect the metabolic activity of the cells. If the metabolic activity increases, this would help the cells colonize the surface, whereas if the metabolic activity decreases, then the cells may become inactive or die.There have been a number of studies that have examined the effects of attachment on bacterial metabolic activity. The first reported observation of this effect was made in 1943, where it was found that bacterial activity increased in the presence of glass surfaces, particularly with low nutrient concentrations (54). Since this first study, researchers have examined how various materials, including glass and polymer surfaces (10, 11, 24-26, 40, 44, 47), silicone surfaces (52), ceramic surfaces (32), dialysis membranes (18), activated carbon (7), clays (43), sands (31, 48), estuary particles (19), and ion exchange resins (46), affect the metabolic activity of attached bacteria.Different mechanisms have been examined in an attempt to explain how surfaces affect bacterial metabo...

“…The result of this treatment was due to increased amine groups on the anode surface which facilitates better attachment by the bacteria which are negatively charged (Silhavy et al 2010). Better attachment in turn influences better electron transfer (Terada et al 2006). Further, functionalization of dimethylaniline groups on carbon cloth anode was done by using the compound 4(N,N-dimethylamino)benzene diazonium tetrafluoroborate to increase the nitrogen groups present on the surface and this functionalization individually was also varied as well as compared with that by ammonia gas treatment (Saito et al 2011).…”

Bioelectricity production involves generation of electricity by anaerobic digestion of organic substrates by microbes. A microbial fuel cell (MFC) is a device that converts chemical energy released as a result of oxidation of complex organic carbon sources which are utilized as substrates by microorganisms to produce electrical energy thereby proving to be an efficient means of sustainable energy production. The electrons released due to the microbial metabolism are captured to maintain a constant power density, without an effective carbon emission in the ecosystem. The various parameters involved in MFC technology toward power generation include maximum power density, coulombic efficiencies and sometimes chemical oxygen demand removal rate which evaluates the effectiveness of the device. Application of microbes toward bioremediation at the same time resulting in generation of electricity makes MFC technology a highly advantageous proposition which can be applied in various sectors of industrial, municipal and agricultural Waste Management. Although the efficiency of MFCs in power generation initially was low, recent modifications in the design, components and working have enhanced the power output to a significant level thereby enabling application of MFCs in various fields including wastewater treatment, biosensors and bioremediation. The following review provides an outline about the components involved, working, modifications and applications of MFC technology for various research and industrial objectives. ARTICLE HISTORY

“…Furthermore, they state that bacterial cell wall structures are likely to very much affect the viability [162] and this should be accounted for in future studies which are likely to investigate bacterial cell-substrate interactions. Whilst Terada and coworkers [161,162] showed that radiation grafting gave rise to an increase in bacterial adhesion, this is contrasted by Nava-Ortiz et al [164] who showed that Candida albicans adhesion can be reduced, preventing the formation of a biofilm on polyethylene (PE) and polypropylene (PP). It should be noted that Candida albicans is a fungus which, although forms a biofilm, has a very different adhesion and growth mechanism when compared to other forms of bacteria.…”

“…In addition, they carried out in vivo studies to AAm and HEMA grafted EPR, showing that CO 2 laser grafting can be employed to enhance the bioactivity of EPR [160]. Radiation grafting has been applied for the development of surfaces for the scientific study and control of bacterial adhesion and growth [34,[161][162][163][164][165][166]. The works of Terada and coworkers [161,162] showed how grafting diethlamine (DEA), ethylamino (EA) and sodium sulphite (SS) onto polymeric surfaces can manipulate bacterial adhesion and viability.…”

On account of the recent increase in importance of biological and microbiological adhesion in industries such as healthcare and food manufacturing many researchers are now turning to the study of materials, wettability and adhesion to develop the technology within these industries further. This is highly significant as the stem cell industry alone, for example, is currently worth £3.5 million in the United Kingdom (UK) alone. This paper reviews the current state-of-the-art techniques used for surface treatment with regards to modulating biological adhesion including laser surface treatment, plasma treatment, micro/nano printing and lithography, specifically highlighting areas of interest for further consideration by the scientific community. What is more, this review discusses the advantages and disadvantages of the current techniques enabling the assessment of the most attractive means for modulating biological adhesion, taking in to account cost effectiveness, complexity of equipment and capabilities for processing and analysis.
